If "STA_AUTOCONNECT 0" has been used to disable automatic connection on
disconnection event and the driver indicates a failure for the data
connection after successful WPS handshake, it is possible to hit a case
where wpa_s->disconnected is set to 1 and further attempts to connect
shall stop.
While "STA_AUTOCONNECT 0" is used to disable automatic reconnection
attempts in general, this specific WPS case can benefit from trying
again even with that configuration for a short period of time. Extend
the wpa_supplicant re-enable-networks-after-WPS 10 second timeout to
apply for ignoring disabled STA_AUTOCONNECT immediately after a WPS

Some APs may send RSC octets in EAPOL-Key message 3 of 4-Way Handshake
or in EAPOL-Key message 1 of Group Key Handshake in the opposite byte
order (or by some other corrupted way). Thus, after a successful
EAPOL-Key exchange the TSC values of received multicast packets, such as
DHCP, don't match the RSC one and as a result these packets are dropped
on replay attack TSC verification. An example of such AP is Sapido
RB-1732.
Work around this by setting RSC octets to 0 on GTK installation if the
AP RSC value is identified as a potentially having the byte order issue.
This may open a short window during which older (but valid)
group-addressed frames could be replayed. However, the local receive
counter will be updated on the first received group-addressed frame and
the workaround is enabled only if the common invalid cases are detected,
so this workaround is acceptable as not decreasing security
significantly. The wpa_rsc_relaxation global configuration property
allows the GTK RSC workaround to be disabled if it's not needed.

Linux packet socket workaround(*) has an impact in performance when the
workaround socket needs to be kept open to receive EAPOL frames. While
this is normally avoided with a kernel that has the issue addressed by
closing the workaround packet socket when detecting a frame through the
main socket, it is possible for that mechanism to not be sufficient,
e.g., when an open network connection (no EAPOL frames) is used.
Add a build option (CONFIG_NO_LINUX_PACKET_SOCKET_WAR=y) to disable the
workaround. This build option is disabled by default and can be enabled
explicitly on distributions which have an older kernel or a fix for the
kernel regression.
Also remove the unused variable num_rx.

When one peer doesn't include a persistent group info in PD Request
the other peer shouldn't report a persistent group usage with this
peer even if such a persistent group exists locally. This condition
could be violated in the previous implementation.
In case a local persistent group exists and the
wpas_p2ps_prov_complete() function is called with persist_ssid parameter
set to NULL, wpa_supplicant reported P2PS-PROV-DONE with persist=<idx>
instead of conncap=<role> parameter.
This happened because the wpas_p2p_get_persistent() function was called
without verification whether the persist_ssid was set to NULL. In this
case the wpas_p2p_get_persistent() returns the first existing persistent
group matching the P2P Device Address without verifying the group's
SSID. After that the group ID is used as persist=<idx> parameter of
P2PS-PROV-DONE event.

It is possible for driver-based BSS selection to end up reassociating
back to the current AP. If wpa_supplicant preferred another BSS, it
would have updated the internal knowledge of the AP's WPA/RSN IE when
requesting a new connection. In the special case of existing association
and new association being with the same BSS that is different from the
wpa_supplicant preference, association event processing skipped the
WPA/RSN IE update. This could result in the following 4-way handshake
getting rejected due to incorrectly detected mismatch with AP's RSN/WPA
IE between Beacon/Probe Response frame and EAPOL-Key msg 3/4.
Fix this by updating the AP WPA/RSN IE on all association events when
driver-based BSS selection is used regardless of whether the BSSID
changes. This could also cover a theoretical case of the AP changing its
RSN/WPA IE at the very moment we try to reassociate back to the same
